An article in Bustle on how COVID-19 vaccines could slow transmission quotes
John A. Sellick Jr., DO, professor of
medicine in the
Division of Infectious Diseases, who said while the most important measure of the vaccines is their ability to prevent severe disease and death, transmission is a big deal, too. “If the vaccines stop the COVID virus from
breeding in your throat and lungs, you’ll carry a lot less of it around, and won’t spread it to others,” according to the article. “While it is unlikely that these vaccines completely stop replication,” Sellick said, “there is evidence that significant proportions of it can in fact be stopped. This will lessen the chance that the vaccinated person will shed virus that then can be transmitted to other people.”
